Abstract

Blood typing by Facilitated tube method, the previous performance that was done disorderly and unstably by 3 tubes will now be performed by reducing the tubes to one and augmenting one special box which decreases human error and therefore improves of quality in any aspect. In what was done previously, due to the number of tubes in the entire test for several simultaneous persons and also the number of typing blood tubes for one of the three-to-four persons, alongside other difficulties that was the probability of mistaken patients' tubes, the amount of wasted time and energy was great and increasing. The purposes of invention: 1. Reducing human error, 2. Reducing waste of time, 3. Reducing expenses, 4. Increasing the factor of safety, 5. Removing the obsolete method and 6. Increasing the safety of patient over injecting blood product.

Description

Determining blood type by tube facilitated

The innovation refers to Medicine, biomedical engineering, Hygiene; Detecting, measuring or recording for diagnostic purposes; Investigating or analyzing materials by specific methods not covered by the preceding groups.

Blood typing test was formerly done on specific slides that is now considered obsolete and illegal. Afterwards, the tube method was substituted that is a safer and more scientific method. In tube method “three” tubes are used to determine the blood type that is, a scientific and international method. Moreover, instead of vibrating the slides on the shaker, after adding reagent antibodies, the tubes are placed in centrifuges with specific revolutions and time and then, proceed to perusal and interpret the results using eyesight and related cadre.

In former methods, due to the number of tubes that were 3 tubes for each person, difficulties were seen during reading test results at final stage of tubes centrifuge. For instance, while removing the tubes from centrifuge, the reordering of tubes was difficult and led to disorder in scanning tubes, interpreting results and reducing accuracy. For instance, once the tube was related to blood type A, the other related to B and Rh, mean that overall 9 variable states were imagined that led to increase of visual illusion.

The second and primary problem that occurs in laboratories and institutes of blood transfusion is that for each person the blood typing is performed, e.g. likely the blood typing of 5, 10, 30 or even more persons are simultaneously done.

Currently, e.g. for almost 30 persons about 90 tubes must consistently and regularly be contained with reagents, become centrifuged and ordered to be scanned.

Increasing the number of tubes and the persons that are to be tested makes the process of blood typing more difficult and error-prone and this is still an ongoing problem.

Presently, other manual methods that centrifuges and tube are not used within, e.g. slide methods all are obsolete and dated that will not be discussed however are now being used as a primary blood typing method illegally and obligatory since they’re easier to perform and have lower human error.

For solving the problem of tube quantity and inconsistency of tube emplacement during reading results in blood typing tube method, each of the three tubes are designed in one tube and for each of distinct spaces a hole is embedded to spill the blood and reagents of blood typing.

Now we have 3 distinct and stable spaces for pouring reagents each of which are labeled e.g. reagent A is always poured into the first cell and human mind gets used to it and a series of human errors get eliminated. Using a tube for each person decreases the errors, besides.

On the box, the place of pouring blood, reagents, and also tubes are numbered so that after centrifuging the tubes each tube is placed on its former position which has the name and number of that particular person.

The box is cuboid which has 8 holes for placing each person’s sample before and after centrifuging and there are 8 holes to place each person’s test tube.

There is a shining system embedded below the box to increase the contrast and resolution during reading.

The box is designed to be additionally responsive for some of the serology slide tests and be usable for slide method if needed to immediately re-verify blood typing results which is a very important property.

On top of the box, there are 3 holes embedded with the height of 2 centimeters that reagents of A, B, Rh are placed into. To provide the needed coldness, one container with the capability of being contained of ice is placed.

Using these methods, decreasing tubes leads to reducing overall coefficient of error.

Applicability of both methods, cell type and back type.

Because of the one-piece tube for each person, the pace and accuracy rises simultaneously and lesser space is needed, besides. Any decrease of mistaken blood typing will increase the coefficient of patient’s safety whom are nominated for blood reception and transplantation since the coincidence of patient’s and donor blood type will 99% fulfillment of the recipient

Because of the possibility of verifying and controlling the authenticity of results via a second person, the confidence coefficient will increase significantly since the major proportion of errors are due to this matter. For instance, the responding occurs after authentic reading of reply during writing the results in the sheet or reception to the system. Thus, re-check of result readings is possible without fully redoing the test and spending more expenses and work force.

Since no redoing of the test is required when suspicious of results of reading and interpreting, the need for redoing the test is omitted and eventually further expenses reduce dramatically.

The patient’s blood sample is placed in first cell. Then the special tube, that is numbered, is placed on the right hand and besides the person’s blood sample. Moreover, the required amount of blood is taken and poured into one the three spaces using the sampler.

This process will be repeated for 7 other blood samples which are related to 7 further persons. Now the tubes will be carried over to centrifuge and after complementing the process and bringing the tubes out, they are placed to their former positions, say each person’s tube will lie alongside their blood sample to determine their blood type.

According to what was described above and demanding need of all domestic laboratories, industrial production is wholly economical and feasible.

1. Three required tubes for this experiment are placed and designed in one tube to avoid the confusion due to the number of tubes and with conditioning due to consistency and repetition of work stages, coefficient of error decreases. In addition to accuracy and authenticity of results, the pace is also improved.
2. Using this method, decreasing the tubes will lead to reduction of coefficient of error.
3. Applicability for both methods, cell type and back type.
4. Because of the one-piece tube for each person, the pace and accuracy rises simultaneously and lesser space is needed, besides. Any decrease of mistaken blood typing will increase the coefficient of patient’s safety whom are nominated for blood reception and transplantation since the coincidence of patient’s and donor blood type will 99% fulfill the recipient
5. Because of the possibility of verifying and controlling the authenticity of results via a second person, the confidence coefficient will increase significantly since the major proportion of errors are due to this matter. For instance, the responding occurs after authentic reading of reply during writing the results in the sheet or reception to the system.
